The Department of Homeland Security contains many diverse organizations
that produce or use maps in daily operation. Audiences for these
maps range from geospatial analysts to the general public. While
individual organizations have their own standards or conventions
for map symbology, there is not a consistent set of symbols used
across the entire Department.

To support increased information sharing across the Department,
DHS Science &Technology Directorate is sponsoring a GeoVISTA
project to document the current use of map symbols in different
homeland security missions, to develop a repeatable process for
expanding symbol sets to support new needs, and to develop new technology
to support symbol sharing and dissemination.
